What is ATJ 9001.1?
The Notice of Change of Address (form ATJ 9001.1, NCA-SC) is the Illinois Supreme Court approved statewide form used to notify the court and the other people in an appeal that your mailing address, your email address, or both have changed.
The form is headed "IN THE SUPREME COURT OF ILLINOIS" and identifies the case by Supreme Court case number, the party names, the appellate district and appellate court case number, the trial court county, the trial court case number and the trial judge. In item 1 you give your name, an optional business or firm name, and the new mailing address and/or new email address. In item 2 you state who you are in the appeal.
The form has four pages. Pages 1 and 2 hold the notice and Proof of Delivery section A. Page 3 adds sections B and C for additional recipients, and page 4 holds the signature block, which carries a statement made under 735 ILCS 5/1-109. The form says it is approved by the Illinois Supreme Court and is required to be accepted. The Illinois Courts page lists it with a companion guide, How to File a Notice of Change of Address, and both show approval dated 07/2025. If you are sending the notice to more than 3 people or lawyers, you complete a separate Additional Proof of Delivery form.
Who needs to file ATJ 9001.1?
Anyone who is part of a Supreme Court of Illinois case and whose mailing address or email address has changed uses this form. Item 2 lists who you can be in the appeal; check only one box:
- Petitioner/Appellant
- Respondent/Appellee
- Attorney for: a named party
- Other: a description of your role
In the case caption, each party also checks whether they are the Petitioner in the Supreme Court (the party that filed the appeal there) or the Respondent in the Supreme Court (the party responding to the appeal).
A licensed attorney may complete the form on behalf of a client by checking the lawyer box on page 4, entering the client's name, and filling in the lawyer name, attorney number, phone, law firm, email and address. Everyone else checks I am completing this form for myself.
Select New Mailing Address, New Email Address, or both, depending on what you are updating. The form is not a general change-of-address notice for other agencies: it is addressed to the Illinois Supreme Court and the other people in your appeal.
When to file ATJ 9001.1
Use the form when your mailing address or email address changes in a case before the Supreme Court of Illinois, so that the court and the other people in the appeal can reach you. The form prints no separate deadline.
The form warns that if you receive court documents by email you must check your email every day, so you do not miss documents from other parties or from the court. That makes it worth sending the notice as soon as the new address is in use.
The notice is served on the other party at the time you file it: the Proof of Delivery section asks for the date and time, with AM or PM, that the document will be sent.
Documents you need
- Additional Proof of Delivery form: file it with this form only if you are sending the Notice of Change of Address to more than 3 people or lawyers, and check the box on page 3 saying you completed it.

How to submit ATJ 9001.1
The form names two steps: serving the notice on the other people in the case, and filing it. The form itself does not print a court address.
- Serve the other party. Complete the Proof of Delivery section. In A, enter the name, mailing address and email address of the person you are sending it to under Rule 11. If that person has a lawyer, enter the lawyer's information. Sections B and C are for a second and third recipient.
- Choose the delivery method. If you and the recipient both have email, you must use one of the first two electronic options: email (not through an EFSP) or an approved electronic filing service provider (EFSP). Otherwise choose mail or third-party carrier with postage or charge prepaid, personal hand delivery, or mail from a prison or jail.
- E-filing. The Illinois Courts page says that to e-file you must first save the completed form as a PDF and "flatten" it, for example by using Print and choosing "Adobe PDF" or "Print to PDF", then open the saved file to check that it looks filled out.
If you are sending the notice to more than 3 people or lawyers, file the Additional Proof of Delivery form with this form. FillingPDF lets you fill out and download the PDF; submission follows the channels above.
Common mistakes to avoid
- Skipping the Proof of Delivery section: the form says you must serve the other party and complete it.
- Checking more than one box in item 2; the form says to check only one box to show who you are in the appeal.
- Using mail or hand delivery when you and the recipient both have email; the form requires one of the first two electronic options in that case.
- Listing the party instead of the party's lawyer when the other party has a lawyer; the form says to enter the lawyer's information.
- Hand delivering the notice to someone other than the party, a family member over 13 at the party's residence, the party's lawyer or the lawyer's office.
- Sending to more than 3 people or lawyers without completing and filing the Additional Proof of Delivery form.
- Checking only one of the update boxes when both your mailing address and email are changing; select and complete both.
- Filling out the PDF on a webpage without saving it first, or e-filing without flattening it; the Illinois Courts page warns that progress is lost and the form must be flattened.
- Signing without typing /s/ before your name when completing the form on a computer.
Frequently asked questions
What is the Illinois Supreme Court Notice of Change of Address?
It is an approved statewide form (NCA-SC, ATJ 9001.1) that a party or lawyer in a Supreme Court of Illinois case uses to report a new mailing address, a new email address, or both. It includes a Proof of Delivery section for serving the notice.
Do I have to serve the other party with the notice?
Yes. The Proof of Delivery section is headed "You must serve the other party and complete this section." Enter the recipient's name, address and email under Rule 11, and the lawyer's information if they have a lawyer.
How do I send the notice if everyone has email?
If you and the recipient both have an email address, the form requires one of two electronic options: email (not through an EFSP) or an approved electronic filing service provider (EFSP). Mail, hand delivery and prison or jail mailing are for when email is not available.
Can I update my email address and mailing address on the same form?
Yes. In item 1, select the boxes for mailing address, email address, or both, then complete each one you selected. Both are updated together if you check and fill in both boxes.
How do I sign the Notice of Change of Address?
If you complete the form on a computer, type /s/ before your name as your signature and print your name. If you complete it by hand, sign and print your name. Your signature is made under 735 ILCS 5/1-109, so a statement you know to be false is perjury.
What if I am sending the notice to more than three people?
Check the box saying you are sending it to more than 3 people or lawyers and complete the Additional Proof of Delivery form. File that form together with the Notice of Change of Address.
Do I need to flatten the PDF before e-filing?
Yes, if you e-file. The Illinois Courts page says to save the form as a PDF first, then flatten it by printing it to PDF so it cannot be changed. Open the saved file to confirm it looks filled out before filing.
Can I fill out the Notice of Change of Address online on FillingPDF?
You can fill out the PDF online on FillingPDF and download or print it. FillingPDF is an independent service and does not file or serve the notice; you do that through the channels the form describes.
